The present invention relates to a bicycle electronic system, and in particular to a bicycle electronic transmission. In particular, the present invention relates to a bicycle electronic system having a remote shut-off/(re)switching device. The invention also relates to a battery unit for insertion into a bicycle electronic system. The invention also relates to a method for remotely shutting down/(re)turning on a bicycle electronic system.

The motion transfer system in the bicycle includes a chain extending between a shaft associated with the pedal crank and a gear associated with the hub of the rear wheel. When there is more than one gear at at least one of the shaft of the pedal crank and the hub of the rear wheel, and thus the motion transmission system is provided with a transmission, a front derailleur and/or a rear derailleur are provided. In the case of an electronic servo transmission, each derailleur includes: a chain guide member, also referred to as a chain puller, that is movable to move the chain between the gears to change the gear ratio; and an electromechanical actuator, Used to move the chain guiding element. The actuator in turn typically includes a motor, typically an electric motor, coupled to the chain guide element by a connecting rod, such as a hinged parallelogram chain, rack system or worm system; and a chain guiding element downstream of the rotor or rotor A sensor for the position, velocity and/or acceleration of any moving part of itself. It is worth noting that terms that are slightly different from the terms used herein may also be used.

The control electronics automatically change the gear ratio, such as based on one or more of the following detection variables, such as the speed of travel, the rotational cadence of the pedal crank, the torque applied to the pedal crank, the slope of the terrain being traveled, the heart rate of the cyclist, and the like, and/or The gear ratio is varied based on instructions that are manually entered by the cyclist via appropriate control members, such as levers and/or buttons.

A device for controlling the front derailleur and a device for controlling the rear derailleur, or in the case of a simple transmission, only one of the two devices is mounted to be easily manipulated by a cyclist, usually mounted on the handlebar Upper, near its handle, where brake levers are also arranged to control the front and rear wheel brakes, respectively. Controls that allow the derailleur and brakes to be driven in both directions are often referred to as integrated controllers.

Conventionally, the means for controlling the front derailleur and the brake lever of the front wheel are arranged close to the left handle of the handlebar, and conversely, the means for controlling the rear derailleur and the brake lever of the rear wheel are arranged close to the right handle.

The aforementioned components are arranged on the bicycle in a vehicle-mounted manner and must be in communication with each other. In addition, the aforementioned components must be powered.

Preferably, but not necessarily, the bicycle electronic system 1 further includes other units that are connected to the bus bar 29.

The second manual command management unit 22 and the second derailleur management unit 24 are thus illustrated, in the above examples, respectively a unit actuated by the left hand and a unit associated with the axis of the pedal crank.

In an alternative embodiment, there may be only a management unit of the front derailleur and corresponding instructions, which is typically actuated by the left hand.

Among other operating units that can be connected to the bus bar 29 in the bicycle electronic system 1, there are a computer circuit 25, a sensor unit 26, a recording unit 27, and a general peripheral unit 28, such as a unit for detecting/treating the pedaling effect. The remotely located command unit, ie one or more copy command units disposed in different positions on the handlebar or other locations, and the like.

As shown in Figures 2 to 5, the bus bar 29 preferably comprises three cables: Ground cable 30, power cable 32 and a single serial communication cable 34. The ground cable 30 is the reference for all potential differences of the system 1, the power cable 32 supplies power to all of the operating units 21-28 connected to the bicycle electronic system 1, and the serial communication cable 34 is connected to all units 21 of the bicycle electronic system 1 - 28 for communication services or error messages or instructions.

As shown in FIG. 2, each of the operating units 21-28 preferably includes a processor 40 and a voltage regulator 42 disposed between the processor 40 and the bus bar 29, more specifically disposed at its ground. A voltage regulator 42 between the cable 30 and the power cable 32.

The processor 40 controls and/or is controlled by the devices dedicated to the operating units 21-28 themselves, which are indicated by the normal function block 44.

The provision of the voltage regulator 42 makes it possible to design each of the operating units 21-28 with a processor 40 that is most suitable for the particular function of the unit itself, as can be appreciated from the above, which can be highly variable. In effect, voltage regulator 42 captures the power provided by battery 20 from busbar 29 and provides processor 40 with the most suitable voltage value.

Although not shown, one or more of the electronic and electromechanical devices illustrated by functional block 44 can be directly coupled to ground cable 30 and power cable 32 to be powered by battery unit 20 via bus bar 29.

Each of the operating units 21-28 also preferably and advantageously includes a modulator or transmitter 48 for the voltage on the communication cable, and a demodulator or receiver 50 for the voltage on the communication cable. Receiver 50 is shown as a separate block, but it can be integrated into processor 40.

Providing a transmitter or modulator 48 and a receiver or demodulator 50 in each unit coupled to the bicycle electronic system 1 allows for direct communication between the various units. In particular, the manual command management unit 21, 22 and/or the sensor unit The 26 can communicate directly with the derailleur management unit 23, 24 to directly apply upshift and downshift commands and receive status information for the derailleur.

In some of the operating units 21-28, the transmitters 48 and/or the receivers 50 may not be present, which of course gives up the communication capabilities (or full capabilities) of these units.

In the illustrated embodiment, the first shutdown/(re)switching device 11 can be removed from the remainder of the bicycle electronic system 1. This advantageously avoids an accidental activation of the first shut-off/(re)switching device 11 and thus avoids an accidental shutdown of the system.

Alternatively, the first shut-off/(re)switching device 11 can be integrated in the system 1, for example in the form of a bistable switch, advantageously connected to the communication cable 34 and the grounding wire of the power supply and communication busbar 29 Between the cables 30.

The second driver 15 is connected between the controlled switch 13 and the communication cable 34 (in an indirect manner, as will be briefly explained), and when the connector 11 is connected (Fig. 3), it disconnects the controlled switch 13. Thereby, the power source 36 is disconnected from the power cable 32. Therefore, the bicycle electronic system 1 is turned off.

For this purpose, the user simply connects the connector 11 to the cymbal 60 of the bicycle electronic system 1 and, if necessary, disconnects/removes the possibility of being connected to the input of the operating unit 21-28 or 埠60 of the cymbal 60. protection cap. In this way, the ground cable 30 and the communication cable 34 of the bus bar 29 are connected to each other (arrow F1).

As described above, the user can connect the ground cable 30 and the communication cable 34 of the bus bar 29 to each other by applying a wire between the ground cable 30 of the bus bar 29 and the communication cable 34, without being provided for dedicated use. The dedicated port 60 of the connector 11 does not require changing the state of the bistable switch integrated in the bicycle electronic system 1.

After the ground cable 30 and the communication cable 34 of the bus bar 29 are connected to each other, the voltage on the cable 35 leading to the communication cable 34 becomes zero, and in particular, the voltage V _C at the node _C becomes zero (V _C =0). The voltage V _A at node A exhibits a value corresponding to the forward voltage of the Schottky diode 16 , for example equal to about 0.2 volts (V _A = 0.2 volts). Therefore, the voltage V _G = V _A at the gate G of the n-channel MOSFET 17 is sufficiently small, for example, 0.2 volt, so that the voltage between the gate G and the source S of the n-channel MOSFET 17 is V. _GS <V _t1 , V _t1 is the critical on-voltage of the n-channel MOSFET 17. The n-channel MOSFET 17 is thus turned off or turned off. Next, in the resistance R5 of the first driver 14, the current does not flow, and the voltage at the node E is equal to the voltage at the node B (V _E = V _B ). As a result, the voltage between the gate G and the source S of the p-channel MOSFET 18 is equal to zero (V _GS =0), that is, greater than its critical on-voltage. Therefore, the p-channel MOSFET 18 is turned off or turned off. Therefore, the power source 36 of the battery unit 20 is actually disconnected from the power cable 32 of the bus bar 29. Therefore, the other operating units 21-28 are not powered, and the system 1 is actually turned off.

It is now assumed that the user wishes to switch on the bicycle electronic system 1 using the shut-off/(re)switching device 10 according to the invention.

For this purpose, the user simply disconnects the connector 11 from the cymbal 60 of the bicycle electronics system, and if necessary, connects the operating unit 21-28 (re) to the cymbal 60, thus the ground cable 30 of the busbar 29 and The communication cables 34 are disconnected from each other (arrow F2). Alternatively, the disconnection can be performed by the user by removing the wires described above or by converting a bistable switch integrated in the bicycle electronic system 1.

After the communication cable 34 the cable 30 is disconnected from the ground, in particular voltage and the voltage on the guide 34 to the wire communication cable 35 is then at node C becomes equal to the bus from the value V _C = 0 A constant value of the quiescent voltage V _q on the communication cable 34 of 29. The quiescent voltage V _{q is set} by the resistors R1 38, R2 39 of the polarizer of the battery unit 20. The term rest voltage _Vq also indicates the voltage measured on the communication cable 34 when no modulator or transmitter 48 is activated in the operating units 21-28 of the system 1. Still voltage V _q is set higher than the voltage at node A V _A, V _A voltage provided by the second driver 15 of the resistor R3 37a and R4 37b.

It should be noted, in this state still occupied by the node C voltage V _q is set to be greater than the open or cut off the Schottky diode isolation means fact means that the node voltage at V _{A A} 16 so that the first Node A of the second driver 15 is effectively isolated from the communication cable 34 of the busbar 29. Therefore, preventing accidental interference on the communication cable 34 causes an unexpected transition of the n-channel MOSFET 17.

Therefore, the voltage V _A set at the node A by the resistors R3 37a and R4 37b of the second driver 15 is also set to a value such that between the gate G and the source S of the n-channel MOSFET 17 voltage V _GS> V _t2, V _t2 is an n- channel MOSFET 17 is turn-on voltage threshold. Therefore, the n-channel MOSFET 17 is turned on or in the path state. Therefore, the voltage V _{B B} becomes zero at the node (V _B = 0). Since the voltage V _E at the node E is equal to the voltage of the power source 36, the voltage between the gate G and the source S of the p-channel MOSFET 18 is negative, and the p-channel MOSFET 18 is turned on or in the path state. The voltage on the cable 33 of the power cable 32 leading to the power and communication busbars 29 coincides with the voltage of the node E, that is, the voltage supplied by the battery unit 20. Therefore, the power source 36 of the battery unit 20 is actually connected to the power cable 32 of the bus bar 29. Therefore, the other operating units 21-28 are supplied with electric power, and the system 1 is actually turned on.

The above system 1 represents an advantageous embodiment of a method for remotely switching off/(re)turning on the bicycle electronic system 1 according to the invention.

Such methods include: When the system 1 is switched off: a) the first shutdown/(re)switching device 11 is activated by the user; and b) in response to the activation, by means of the second shutdown/(re)switching device 12 The battery unit 20 is disconnected from the power supply and communication busbars 29; when (re)connecting the system: a) the first shutdown/reconnection device 11 is deactivated by the user; and b) is responsive to the deactivation The battery unit 20 is connected to the power supply and communication bus by means of a second shutdown/(re)switching device 12.

Preferably, activating the first shutdown/(re)switching device 11 includes connecting the power source of the bicycle electronic system 1 and the ground cable 30 and the communication cable 34 of the communication busbar 29 together.
